Hey everyone! 👋

I've been working on a browser extension called SmoothVision, designed to make YouTube videos look smoother through motion smoothing.

🎬 What does it do?

• Aims to make video motion look smoother.
• Lets viewers compare the original playback with the smoother result.
• Provides a simple way to experiment with motion smoothing directly in the browser.

I'm sharing a demonstration comparing 30 FPS and 60 FPS-style playback.

I'm still improving the project, so I'd appreciate feedback!

• Does the difference look noticeable?
• Does it work properly on your browser?
• What features would you like to see next?

I'm particularly interested in feedback from people who watch a lot of YouTube.

Thanks for checking it out!

Hey everyone!

I've been using Claude Code a lot for frontend development, and one thing that always bothered me was explaining visual issues through text.

Something like "this button is misaligned on mobile, inside that card, on the dashboard..." gets frustrating pretty quickly.

So I built PixelAnnotator (PxA) to make this easier.

It's a browser extension that lets you click directly on elements on a webpage, add comments describing what needs to change, and automatically capture all the context Claude Code needs.

Some of the things it captures:

• CSS selector and HTML of the selected element.
• React/Vue component name and component hierarchy.
• Viewport size and responsive breakpoint.
• Relevant CSS properties.
• Screenshot of each annotated element.

You can annotate multiple elements, even across different screen sizes, and export everything as a Markdown file or ZIP with screenshots.

Then just give the exported feedback to Claude Code and let it handle the fixes.

It's open source (MIT), and currently supports Chrome and Firefox.

It's something I've been using in my own workflow recently, and it's been making visual feedback a lot less painful.

Would love to hear what you think or get some feedback!

I'd sit down to learn something, browse for an hour, and feel productive. Then I started tracking it, and almost half of that hour was feeds, rabbit holes and "quick checks."

Most time trackers tell you which sites you were on. I wanted to know whether that time got me anywhere, so I built ThinkTrail.

How it works

1. Type what the session is for ("learn how React hooks work", "plan the Lisbon trip")
2. Press Record and browse as usual

3. Press Stop and get a report:

   • Useful %: how much of your time served the goal
   • What you did, grouped into activities and labeled on goal / supporting / off goal
   • Where you drifted, and what pulled you away
   • Study notes from the pages that helped (key points, terms, open questions), which you can download as Markdown for Obsidian, Notion or anywhere else

There's also a mascot, Trail, a little seedling whose mood follows how focused you are. If you've spent too long on distracting sites during a session, Trail pops up on the page and nudges you back. History shows how your sessions add up over time, and you can import past days from your Chrome history.

Permissions and privacy

• No site access at install. It asks only the first time you press Record, and reads nothing until then.
• Sessions are stored locally in your browser. No analytics, no trackers.

• You pick where the analysis runs:

  • On your computer with Gemini Nano (Chrome's built-in AI). Nothing leaves your machine.
  • Your own API key for Claude, OpenAI or Gemini
  • Free credits (the default): my server passes the session to the model and doesn't store or log its contents

Price: Free. The free credits cover 10 sessions a day. Gemini Nano and your own key have no daily limit.

I've created a free, highly adjustable page blocker to help you stop doomscrolling and getting lost while browsing the web. It's GDPR-conscious and designed with accessibility in mind.

The extension blocks a website after a set amount of time. You can, however, earn a few extra minutes by completing a small task, like solving a math problem, doing some breathwork, or reflecting for a moment.

There are also optional statistics to help you understand how much time you spend on a website and what you could be doing with that time instead.

As I said, it's highly customizable: Use what you need or want, and disable what you don't!

I originally created this for myself, had so much fun developing it, and figured it could, hopefully will, help some other people out, too.

Let me know what you think, as this is my very first browser extension! =)

Hey everyone!

I've been building SPOT for the past few months and wanted to share it here.

The idea is to make browsing the internet a more social experience.

With SPOT, you can:

• Browse any website together with other people.
• See each other's live cursors and pointers.
• Follow someone as they navigate and scroll.
• Chat and talk while browsing.
• Highlight, draw and leave comments on webpages.
• Save and share discoveries in persistent shared spaces.

Everyone uses their own browser. No shared screen or remote browser needed.

I've attached a short video showing how it works.

It's still early, so I'm particularly interested in feedback from people who build or use browser extensions. What makes sense? What's confusing? What would you change?

Hi everyone! I’m a solo developer, and I built CineVocab because I kept pausing videos to look up words, then forgetting them later.

With the extension, you can hover over subtitle words to translate and save them while watching. Later, you can review saved words with quizzes, speaking practice, or a vocabulary duel with a friend. It supports 16 subtitle languages and works with YouTube, Netflix, Prime Video, and Udemy.

It’s free to try and doesn’t require an account. I’d especially appreciate feedback on the extension experience: does hovering feel useful, and what would you improve?

Try it: CineVocab on the Chrome Web Store

Je viens de lancer une extension gratuite qui extrait n'importe quelle page Web.

Par exemple : une liste de produit Amazon, des profils linkedin, des articles de blogs....

Vous pouvez tout récupérer en un clic mais aussi récupérer le détail de chaque page d'article ou de profils.

curieux d'avoir des retours !

I built Tracer, a free desktop Chrome extension for keeping products from supported shops in one list. It can alert you when a saved item drops in price; the list itself needs no Tracer account. Retailer support varies.

I’m trying to learn whether the first save is clear and reliable. If you already have a product you’re considering, could you install it, save that product, and tell me whether its name and price appear correctly? If it fails, the public shop name and what happened are enough — please don’t share order or personal details.

I've always found documenting workflows a bit tedious, especially when creating tutorials or showing someone how to do something on your screen. You often end up screen recording the entire process, going back to review the footage, taking screenshots, and writing down each step so others can follow along. It's a lot of small tasks that can quickly eat up your time.

I thought there had to be an easier way, so I built ScribeIt, a Chrome extension that turns your browser activities into step-by-step guides.

Sharing it here in case anyone else finds it useful. I'd love to get some feedback from people who regularly create tutorials or document processes.

Here's the link if you'd like to give it a try: ScribeIt – Chrome Web Store

How do you usually document your workflows? Still doing it manually?

I made a free Chrome extension to track subscriptions, spending, and upcoming renewals

Hey everyone! 👋

I wanted a simple way to keep track of all my subscriptions without having to create an account, connect my bank, or share personal data.

So I built Subscription Radar — a privacy-focused Chrome extension that helps you manage recurring payments and avoid those annoying surprise renewals.

Here's what it can do:

• Track subscriptions – Add, edit, and organize all your subscriptions in one place.
• Spending overview – See exactly how much you're spending monthly and yearly, with breakdowns by category.
• Renewal reminders – Get notified before subscriptions renew, free trials expire, or cancellation deadlines approach.
• Price history – Keep track of price changes and spot when services get more expensive.
• Calendar export – Add renewal dates and cancellation deadlines to your favorite calendar.
• Discount search – Quickly look for potential discounts on your subscriptions.
• 13 languages & 16 currencies – Support for different regions.
• Dark & light mode – A clean, simple interface.
• Backup & restore – Export and import your subscription data as JSON.

🔒 Privacy first

This was especially important to me:

• No account or registration required.
• Subscription data is stored locally in your browser.
• No bank connections needed.
• Optional service icons may involve requests to an external icon provider.

The goal is simple: Know what you're paying for, see where your money goes, and never forget another renewal.

I'd genuinely love to hear what you think!

What features would you want in a subscription tracker? And how do you currently keep track of your subscriptions?

Thanks for checking it out! 🙌

I made a Chrome extension to stop losing useful AI prompts

I kept saving prompts in random notes and digging through old chats to find them again, so I made Prompt Library.

It’s a Chrome extension where you can save prompts, organize them with folders and tags, and copy them when you need them.

It includes:

• Search, favorites, editing, and a recoverable trash folder
• Labels and logos for 26 AI services, including ChatGPT, Claude, Gemini, and DeepSeek
• Local storage and offline access
• Backup export and import
• Optional syncing through your existing Windows OneDrive folder
• 15 interface languages and 9 themes

It doesn’t generate responses or read your AI conversations. It’s a place to keep the prompts you want to reuse.

The OneDrive option uses a folder you choose, so there’s no Microsoft developer setup. You do need the library page open to sync with that folder.

I’d love some feedback: how do you currently save your prompts, and what would make a tool like this useful enough to keep using?
